Which of the following is a key document ACOs must maintain during investigations?

The maintenance of incident reports and photographs is crucial for Animal Control Officers (ACOs) during investigations. These documents serve as official records of the incidents they respond to, including details such as the location, involved parties, animals, and any actions taken. Incident reports provide a structured overview of the situation, ensuring transparency and accountability in the ACO's work. Additionally, photographs can capture visual evidence that reinforces the details noted in the reports, which is vital for any potential legal proceedings or follow-up actions. Together, these records help establish a comprehensive understanding of each case and support accurate documentation, which is indispensable for effective case management, reporting, and compliance with regulations.
